UNITED J. CARMICHAEL AND ALBERT M. WU'NDERLICH, OF NEW HAVEN, OONNECT-IGUT, ASSIGNOR TO THE GREIST MANUFACTURING COMPANY, A OGRPORATION OFCONN ECTIGUT SEWING-MACHIIQ'E-AT'I'ACI-IMENT HOLDER Application filedDecante- 29, 1927. Serial No. 243,350.

This invention relates to a holder for sewing machine attachments bywhich various attachments may be conveniently secured to the'presser-footof a sewing machine. The improved attachment holderpreferably consists of a clamp comprising two jaws adapted to engage thehorizontal or vertical portion of a sheet metal presser foot, said jawsbeing preferably forced together for a clamping operation by means of athumb screw passing loosely through the upper jaw and tapped in thelower jaw. Integral with this clamp is an extension to which anattachment or attachment support may be secured in any proper manner, asby rivets.

In the accompanying drawings Fig. l is a side view of one form of theimproved attachment holder, showing the same in operative relation tothe presser foot of a sewing machine, with the braider or corder mountedthereon. Fig. 2 is a rear View of the attachment holder looking from theright of Fig. 1, with the part of the presser foot engaged by the clampinsection. Fig. 3 is a plan view of the attachment holder shown in Figs.1 and 2 with the braider or corder omitted. Fig. 4 is a plan View of anapproved form of the improved attachment holder with a binder mountedthereon. Fig. 5 is a plan view of the attachment holder with an'edge-stitcher guide attached thereto. Fig. 6 is a plan View of theattachment holder shown in Figs. 1 and 5, without any attachment. Fig. 7is a section on line ?7.'

Fig. 4. Fig. 8 is a View similar to Fig. 2, showing a cam lever forforcing the jaws of the clamp together. Figs. 9 and 10 show a form ofclamp extension adapting the clamp to be attached to the vertical partof the presser-foot, and F igs; 11 and 12 illustrate a form of clampsimilar to that shown in Figs. 9 and 10 but adapted to engage a sew ingmachine presser-bar. 7

Referring to the drawings, 12 denotes the foot portion of a sheet metalpresser foot of well known form, and 13 denotes the upper horizontalpart of the shank of saidpresser foot. The improved attachment holdercomprises a clamp 16 having upper and lower jaws, and, integral with thelower jaw of plication Serial said clamp, in the form of the inventionshown in Figs. 1 to 8, inclusive, is a depending part 17 having at itslower end'an'integral horizontal extension 18, these parts 17 and 18constituting an integral extension to which a sewing machine attachmentmay be secured. Passing loosely through the upper of said clamp, andtapped in the lower jaw thereof, is a thumb screw having a knurled head19. A washer 20 will preferably be interposed between the shoulder ofthe thumb screw and the upper jaw of the clamp 16.

To prevent displacement. of the holder relative to a presser-foot shankto which said holder isto be secured, and to facilitate the positioningof the holderon the presser-foot CPI shank, the jaws of the clamp 16 arepreferably provided with shoulders 27- which engage the sides of thepresser-foot shank 13, as clearly shown in the drawings.

In Fig. 1 a braider or corder 21 is shown as being mounted upon aninclined support 22 the lower horizontal part of which is shown as beingriveted tothe horizontal ex-f' tension 18.

This braider or corder forms no part of the present invention, the samebeing fully shown and described in our ap- No. 225,916, filed October13,1927.

Fig. 4- shows the improved attachment holder adapted for supporting abinder attachment 28, this form of the holder being the same as thatrepresented in Figs. 1, 2 and?) excepting that the horizontal extension18 at the lower end of the depending portion of the clamp member isprovided with a lateral e'Ktension'18 on which the binder support24. ismounted.

Fig. 5 shows an edge 'stitcher guide 25 mounted on a holder of the sameform asithat illustrated in Fig, 4, the holder illustrated:

' in Figs. 4c and 5 being'shown in plan in ing said lugs,thisconstructionpermitting v by plate springs slight lateral adjustmentsof the parts 2 and 25, said parts being frictionally held in place 28beneath the heads of the rivets 26.

Fig. 8 is a View similar to Fig. 2, but shovw ing a cam lever 19*,instead of a set screw, for closing the jaws of the clamp 16 together.Figs. 9 and 10 show a construction of clamp adapted to engage thevertical portion 19 of the presser foot 12 by virtue of the fact thatthe extension 1'? is in line with the clamp instead of being at rightangles thereto as in the construction most clearly shown in Figs. 1 and2.

Figs. 11 and 12 show a form of clamp similar to that illustrated inFigs. 9 and 10 but with the jaws of the clamp made in'suitable form forembracing a sewing machine presser bar 29.

From the foregoing it will be understood that the invention provides anefficient sewing machine attachment holder adapted to be secured toapresser member of a sewing machine and consisting, except for the setscrew or cam lever, of a single piece of sheet sewing machine attachmentmay be supported, said clamp comprising two jaws adapted to receivebetween them a part of a sheet metal presser foot, and means by whichsaid jaws may be closed together, said jaws having shoulders tov preventdisplace ment of the holder.

5. A one-piece sewing machine attachment metal (preferably steel) sothat it may be made at little expense.

Having thus described our invention we claim and desire to secure byLetters Patent 1. A one-piece sewing machine attachment holdercomprising a clamp adapted to embrace a sewing machine presser memberand consisting of two integral sheet metal jaws, said clamp having,integral therewith, an extension to which a sewing machine attachmentmay be secured, combined with means for forcing the jaws of said clamptowards each other in rigidly affixing said clamp to the presser member.H

2. A one-piece sewing machine attachment holder comprising a clampadapted to embrace a sewing machine presser member and consisting of'twointegral sheet metal jaws, said clamp having, integral therewith, anextension to which a sewing machine attachment may be secured, combinedwith means for forcing the jaws of said clamp towards each other in thepresser shoulders to prevent holder.

3; A one-piece sewing machine attachment rigidly affixing said clamp tomember, sald jaws having displacement of said "holder consisting of aclamp havingan in- ;tegral depending part provided at its lower end witha horizontal extension by which a sewing machine attachment may besupported, said clamp COIHPIlSlIlg two jaws adapted to receive and meansby 4. A one-piece sewing machine attachment holder consisting 01 a clamphaving an integral depending part provided at its lower end with ahorizontal extension by which a between them a part of.
